It's not a proper square root, but you're looking for a number between 25 and 26 (<span>25.6515106768)</span>
Answer:
thank youuu :))) <<<<<<<<<<<
We will use demonstration of recurrences<span>1) for n=1, 10= 5*1(1+1)=5*2=10, it is just
2) assume that the equation </span>10 + 30 + 60 + ... + 10n = 5n(n + 1) is true, <span>for all positive integers n>=1
</span>3) let's show that the equation<span> is also true for n+1, n>=1
</span><span>10 + 30 + 60 + ... + 10(n+1) = 5(n+1)(n + 2)
</span>let be N=n+1, N is integer because of n+1, so we have
<span>10 + 30 + 60 + ... + 10N = 5N(N+1), it is true according 2)
</span>so the equation<span> is also true for n+1,
</span>finally, 10 + 30 + 60 + ... + 10n = 5n(n + 1) is always true for all positive integers n.

Answer:
b^20
Step-by-step explanation:
when the exponents have one inside and the other outside, they are multiplied.
It would be B or 1,625 because percentages are going to always involve multiplication. if I'm wanting to find a percentage you do .25 times 6,500 which leaves you with 1,625.
